SSD vs HDD RAID in Servers and Storage

SSDs in servers deliver performance, whether measured in IOPS or GBps or latency, that is just plain impossible with disks. SSD capacity is now greater than that of performance disks. Price is the factor that still keeps many organizations away from deploying servers with SSD storage when the improved performance is not a significant benefit. The better reliability of SSD might be more important. Continue reading SSD vs HDD RAID in Servers and Storage

Storage Capacity: TB vs TiB

For years, ion has reported usable capacity of disk and SSD storage in GiB and TiB instead of GB and TB. Why?  And what’s the difference?  Basically, 1 GB = 1,000,000,000 bytes while 1 GiB = 1,073,741,824 bytes. That is about 7%!  Look at ion‘s SR-71mach6 SpeedServer or PS StorageServer for examples of capacity reporting. You can learn more about the differences in the Continue reading Storage Capacity: TB vs TiB

ion SR70mach5 SpeedServer™

The new performance-optimized SSD-RAID Server from ION Computer Systems® is also price-optimized.  Based on ION’s award winning SR-71mach5 SpeedServer family and technology, the SR-70mach5 SpeedServer™ is a 1U rackmount server with optimized RAID and Standard Endurance SSDs. The SR-70mach5 SpeedServer is based on an Intel® ServerBoard and comes with (2) 3.4GHz 8-core Intel® Xeon® V4 processors, 9TB RAID 5 usable with Intel® DC SSDs Continue reading ion SR70mach5 SpeedServer™

Observations on NVMe SSDs in Server Applications

NVMe SSDs offer a direct PCI express connection to storage, skipping the overhead and latency that comes with assuming that storage is rotating media when it is really SSD. Individually, NVMe SSDs offer a significant performance advantage over SATA SSDs. Over the last year, ION has invested much time and energy in benchmarking the performance of NVMe SSDs in servers. In practice, the applications Continue reading Observations on NVMe SSDs in Server Applications

Disk-Impossible File Server

ION® Computer Systems, Inc. recently published benchmark results for its SR-71mach5 SpeedServer™ running Microsoft® Windows® Server 2012 R2 with the SMB 3.1 protocol.  Yes, the performance is “Disk-Impossible!”.  A single 2U “mach5” system costing under $80k served 64kB random reads at 10 Gigabytes per second and delivered 8kB random reads at 1 million Input/Output Operations per second.  Average latency as low as 1ms was Continue reading Disk-Impossible File Server

SSD RAID

There are many opinions on the benefits and liabilities of SSD RAID floating around the Internet; ION’s experience with SSD RAID differs dramatically from some of it.  ION’s SR-71mach4 SpeedServer™ is a server and storage platform optimized for and with SSD RAID.  This article shares some observations on the performance and endurance of SSDs in RAID usage, and examines and compares performance in different Continue reading SSD RAID

SSD Performance has System-wide Effects

The impact of SSDs on I/O related performance in a server is dramatic. Unleashed from the mechanical limitations of spinning disks, a single server can perform 10s or 100s of thousands of I/O Operations per second, IOPS, instead of just a few thousand.  Without long I/O waits, processor, RAM and RAID controllers can all get much busier, but the impact on humbler pieces of Continue reading SSD Performance has System-wide Effects
